The CVS HEAD should be fine.  I don't know about which Cheetah
version is most appropriate.

As far as I know, there's not yet any optimization option to G++
which makes it perform as fast as C code on most of the benchmarks.
I would suggest *not* using -O3; it generally actually makes code
with heavy use of inlining slower than -O2.

Thanks,
